July. Start of the season, a few hours per night.

F/2.8. Cheap lens. Aperture wide open.

Near Moscow. July. The Milky Way is not visible to the naked eye. It's surprising that anything came out in the photo at all.
Center crop, because I don't have a patch of sky where trees, houses, etc. don't fit into 16mm. I had to cut them out.

Processing:
PixInsight. WBPP crashed with out of memory (too many files, 64 GB RAM wasn't enough). I had to use the LN file for processing (LN reference generation)
crop. Graxpert BGE. BlurX, NoiseX, HT_Stretch, StarX.
Starless: Graxpert BGE, red mask.
